I voted "yes."
Since day one, both Cindy and George have been Casey apologists. That, in and of itself, is not illegal, but tampering with evidence is illegal. Withholding evidence or information in a criminal investigation is also illegal. Lying in a criminal investigation to obscure or obstruct the investigation is illegal.
As more and more facts have been made public, it's become clear that there's been evidence tampering - the washing of Casey's slacks that were found in the car that Cindy said "smelled like the car", is just one example.
George's story about the gas can theft is suspicious, and it was sometime in early August that OCSO came to the Anthony home and confiscated the "stolen" gas cans, along with clothing found in the car. I believe George was withholding evidence.
I first became suspicious of George and Cindy on June 18th or 19th. At that time, they gave a lengthy interview in their home with a local news media. One would expect grandparents in a similar situation to be emotional - their two-year-old granddaughter had been missing for more than a month and they believed that she had been kidnapped. Yet, there wasn't a tear shed, nor any fear for her safety expressed.
In the interview that lasted about 20 minutes, they spend a great deal of time telling about child safety in their home - how the shed is always locked and only they have the key; how they're careful to make sure the pool ladder is away from the pool when it's not in use; and how Casey always spent time in the yard with a shovel digging up bamboo shoots so Caylee wouldn't step on them in her bare feet.
As the weeks wore on, it became apparent that the Anthonys knew then, just two or three days after Casey was arrested, what had happened, and were laying the ground work for what they knew would eventually be revealed publicly..........the borrowing of the shovel, the locked shed, and the pool ladder.
In just the past few days, Cindy's attempt to stop the TES search for Caylee's remains, telling Tim Miller he's to look for a live Caylee, is a blatant obstruction of justice, interfereing with the investigation. It's fortunate that LE stepped in asking Tim to stay and continue the search, and even contributing money, boats, and manpower to the search effort.
